Pulp chinhu chine fibrous chinowanikwa kubva kune chirimwa fiber nenzira dzakasiyana dzekugadzirisa.Inogona kukamurwa kuita mechanical pulp, makemikari pulp uye kemikari mechanical pulp maererano nekugadzirisa nzira;inogona zvakare kukamurwa kuita pulp yehuni, mashanga, hemp pulp, tsanga pulp, nzimbe pulp, bamboo pulp, rag pulp uye zvichingodaro zvinoenderana nefiber mbishi zvinhu zvinoshandiswa.Inogona zvakare kukamurwa kuita yakanatswa pulp, bleached pulp, unbleached pulp, yakakwirira-yegoho pulp, uye semi-kemikari pulp zvinoenderana nekuchena kwakasiyana.Kazhinji inoshandiswa mukugadzirwa kwepepa uye kadhibhodhi.Yakanatswa pulp haingoshandiswe chete kugadzira mapepa ehunyanzvi, asi zvakare inowanzoshandiswa seyakagadzirwa kugadzirwa kweselulosi inobuda senge cellulose esters uye cellulose ethers.Inoshandiswawo mumafibhi akagadzirwa nevanhu, mapurasitiki, machira, mafirimu, pfuti uye mimwe minda.
Traditional pulping inoreva nzira yekugadzira yekuparadzanisa chirimwa faibha mbishi zvinhu zvechisikigo kana zvakasvibiswa pulp nenzira dzemakemikari, nzira dzemuchina kana musanganiswa wenzira mbiri idzi.Maitiro anowanzo shandiswa kupuruzira, kubika, kuwacha, kuongorora, kuchenesa, kuchenesa uye kuomesa chirimwa faibha zvinhu.Nzira itsva yebiological pulping yakagadziridzwa munguva dzazvino.Chekutanga, mabhakitiriya akakosha (white rot, brown rot, soft rot) anoshandiswa kunyatso kuodza iyo lignin chimiro, uyezve mechanical kana makemikari nzira dzinoshandiswa kupatsanura yasara cellulose., kuchiteverwa nokucheneswa.Muchiitiko ichi, zvipenyu zvakaora uye zvakazarura zvizhinji zve lignin, uye nzira yemakemikari inongoshandiswa sebasa rekubatsira.Kuenzaniswa nemaitiro echinyakare, zvigadzirwa zvemakemikari zvinoshandiswa zvishoma, saka zvishoma kana kusave nemarara emvura anogona kuburitswa.Iyo inzira ine hushamwari pulping nzira., Yakachena pulping nzira.
